| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force or stretching the O-ring during installation. | Handle the O-ring with care, allowing it to seat naturally within the groove to prevent damage and ensure a proper seal. |
| Installing the O-ring into a contaminated or damaged groove. | Thoroughly inspect and clean the groove before installation. Address any nicks, burrs, or sharp edges that could compromise the O-ring's integrity. |
